Since #225 added forced flushing to
DeflaterOutputStreamit will run the deflate state machine even if it's not supposed to be used. This did not happen before since it were always in a state where it did not need more data when usingCompressionMethod.Stored.By overriding the
Flush()method inZipOutputStreamwe can skip the forced deflate flush when it isn't used.Should fix #398 and #391
